Alkali soil has a pH level above 8.5, indicating it is basic or alkaline in nature. Soils with pH values higher than 8.5 can affect the availability of nutrients to plants, potentially leading to nutrient deficiencies. This alkalinity is often a result of the presence of basic minerals, such as sodium carbonate, in the soil.
